laser doppler velocity measurement








abstract


this experiment is to measure two flow profiles at laminar flow and one profile at turbulent flow and determine the flow velocity at the axis of the tube by applying laser doppler velocimetry technique.
the three fluid velocities selected for the experiments are 1.8 ms, 4.4 ms and 46.3 ms.
we will see that for the velocities ms and ms the flow profile is laminar and for the velocity of ms the flow profile is turbulent.
